NOVELTY - The utility model relates to the technical field of coating, especially a special coating structure for titanium-based polymer alloy heat exchanger, comprising a high temperature resistant heat conducting layer, a conductive silver layer, an anti-corrosion layer, an antibacterial layer and micro-capsule antibacterial agent particles; by setting the high temperature resistant heat conducting layer, it can accelerate the heat conducting, improve the radiating effect; The high temperature self-repairing conductive fulmargin is subjected to external force or fatigue in the internal part to generate micro-crack in the high temperature using process, so as to reach the double repair of crack and conductive network; through the phenolic epoxy resin, epoxy modified organic silicon resin and graphene dispersion are synergistic to make the coating with corrosion resistance, hydrophobic and high temperature and high pressure steam blowing; loading nano-antibacterial agent with porous material, then performing micro-capsule coating method, avoiding the antibacterial agent added in the coating migration, easy to loss, at the same time, it has excellent antibacterial effect, improving the long-lasting and antibacterial life of the antibacterial agent.
